Sayama Domain

The Sayama Domain was a feudal domain of the Tokugawa Shogunate from Kawachi Province, part of Osaka Prefecture. They were ruled by the Hojo clan, enfeoffed in the domain by Ieyasu Tokugawa after the 1600 Battle of Sekigahara, with Ujinao Hojo's adoptive son Ujimori Hojo becoming the first daimyo. The Sayama backed Emperor Meiji in the Boshin War.
